  When trying to run the sample for the FirstSOAService an error occurs when the program is deployed to any other machine than the head-node.
  I compiled the following code :
  ---------------------------------------------------------------------------------
  namespace Microsoft.Hpc.SOASample.FirstSOAService{
      using System;
      using Client.ServiceReference1;
      using Microsoft.Hpc.Scheduler.Session;
      using System.Collections.Generic;
      using eNose_Aethena.Generic;
      using eNose_Aethena.Generic.Datasets;
  
      class Program {
          static void Main(string[] args){
              SessionStartInfo info = new SessionStartInfo("ENO-AP5", "CalculatorService");
              using (Session session = Session.CreateSession(info)){
                  Console.WriteLine("Session {0} has been created", session.Id);
                  using (BrokerClient<ICalculator> client = new BrokerClient<ICalculator>(session)){
                      AddRequest request = new AddRequest(1, 2);
                      client.SendRequest<AddRequest>(request);
                      client.EndRequests();
  
                      foreach (BrokerResponse<AddResponse> response in client.GetResponses<AddResponse>()){
                          double result = response.Result.AddResult;
                          Console.WriteLine("Add 1 and 2, and we get {0}", result);
                      }
                      client.Close();
                  }
                  session.Close();
              }
  
              Console.WriteLine("Done invoking SOA service");
              Console.WriteLine("Press any key to exit");
              Console.ReadKey();
          }
      }
  }
  ---------------------------------------------------------------------------------
  Running this code on the Head Node results in the following output
  ---------------------------------------------------------------------------------
  Session 56 has been created
  Add 1 and 2, and we get 3
  Done invoking SOA service
  Press any key to exit
  ---------------------------------------------------------------------------------
  This is the expected output.

  Trying to run the code on any other machine ( I tried my develop machine and a Compute Node inside the Cluster) result in the following error
  ---------------------------------------------------------------------------------
  Unhandled Exception: Microsoft.Hpc.Scheduler.Session.SessionException: Unknown error occured: {0}.

  ---------------------------------------------------------------------------------
  
  I can not find what might be causing this error..
  I'm sure it shoud be possible to run this code from another machine.
